lithtrix_blob_search

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description discloses the API key requirement and quota sharing, which are important behavioral traits not covered by annotations (none exist). However, it omits details about response format, error handling, and idempotency, leaving gaps for a tool with no annotation safety net.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences long, front-loaded with the endpoint and core purpose, and every sentence adds value (endpoint, purpose, quota sharing, auth requirement). No excess wording.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers endpoint, purpose, auth, and quota context. However, given no output schema, it would benefit from briefly indicating the return structure (e.g., 'returns matching chunks with scores'). As is, it is slightly incomplete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already provides complete descriptions for all three parameters (q, limit, threshold) with 100% coverage. The description adds no additional parameter semantics beyond what is in the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it performs 'semantic search over parsed chunks' and distinguishes from siblings by mentioning it 'shares quota with web search'. The verb and resource are specific and unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides context (searches blob chunks, shares quota with web search) that implies when to use this tool versus the web-based lithtrix_search, but does not explicitly state when not to use it or name alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
